To accomplish the task of creating a basic Python web server that displays "hello world", containerizing it with Docker, and hosting it on an EC2 instance, you can follow the steps below:

1. Create a Python Web Server:

   Create a Python file named app.py with the following code:

   from http.server import BaseHTTPRequestHandler, HTTPServer
   
   class SimpleHTTPRequestHandler(BaseHTTPRequestHandler):
       def do_GET(self):
           self.send_response(200)
           self.end_headers()
           self.wfile.write(b'Hello, World!')
   
   server_address = ('', 8000)
   httpd = HTTPServer(server_address, SimpleHTTPRequestHandler)
   httpd.serve_forever()
   

2. Create a Docker Container:

   Create a Dockerfile with the following content:

   FROM python:3.9
   COPY app.py /app.py
   CMD ["python", "/app.py"]
   

3. Build and Run the Docker Container:

   Build the Docker image:

   docker build -t hello-world-server .
   

   Run the Docker container:

   docker run -d -p 8000:8000 hello-world-server
   

4. Host it on EC2:

   • Launch an EC2 instance.
   • Install Docker on the EC2 instance.
   • Copy the Docker image to the EC2 instance.
   • Run the Docker container on the EC2 instance.

5. Provide Details:

   • IP Address/Hostname of the server: [Your EC2 Public IP/Hostname]
   • Docker Repository: [Provide the repository link if you pushed the image to Docker Hub]
   • Docker Code Details: [Provide the Dockerfile content]

• Ensure that port 8000 is open in the security group of your EC2 instance.
• Modify the security settings and configurations as needed based on your requirements.

By following these steps, you will have a basic Python web server displaying "hello world" containerized with Docker and hosted on an EC2 instance.
